Lenovo Z470 service material in a 1.46 MB RAR archive, with the name also carrying 989 PCH. That token probably refers to the Intel platform controller hub, but the name does not say more and no board number is given. A file of this size typically holds a schematic for following rails, the power-up sequence and signal paths around the chipset. Before relying on it, read the board code and revision printed on your Z470 motherboard and make sure they match what the extracted document shows.
